Larger worlds cannot load

After the recent update, larger worlds made before the update will not load. For context, my game was installed on an external hard drive. This update forced me to move it to my internal hard drive. When I attempt to open them, my Xbox shows the “syncing with xbox” and syncs to the cloud. Then, it shows the following message in Minecraft: “Can’t sync this worlds cloud data with your device. Please check your Internet connection and try again.” With other smaller worlds, they still open as normal.
